18. Analysis of Forces at Each Meter Forces at Meter 0 There are no forces. At meter 0, the car is at zero speed.

19. Analysis of Forces at Each Meter Continued Forces at Meter 1 Forces are unbalanced in the forward direction. At meter 1, the car is speeding up. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

20. Analysis of Forces at Each Meter Continued Forces at Meter 2 Forces are unbalanced in the forward direction. At meter 2, the car is speeding up. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

21. Analysis of Forces at Each Meter Continued Forces at Meter 3 Forces are unbalanced in the forward direction. At meter 3, the car is speeding up. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

22. Analysis of Forces at Each Meter Continued Forces at Meter 4 Forces are balanced. At meter 4, the car is at constant speed. Force exerted by balloon on car. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

23. Analysis of Forces at Each Meter Continued Forces at Meter 5 Forces are unbalanced in the backward direction. At meter 5, the car is slowing down. Force exerted by air on car. Force exerted by axle on straw. Force exerted by ground on wheels.

24. Project Conclusion Write your project conclusion here. Be sure to answer the following questions: How were you able to maximize the forward force of the balloons? How did you minimize backward forces of friction and drag? What could you have done better to make your car go further and faster? How did your car perform compared to other cars in the class. What have you learned by doing this project? WARNING FROM MR. G: This file is a template and example of the PowerPoint you and your partner must create using YOUR data. Without effort in analysis using your own data, graphs, photos, and adjusting forces that apply to the motion of your car, YOU AND YOUR PARTNER WILL NOT RECEIVE CREDIT FOR THIS PART OF THE PROJECT.
